The DLR rocket launcher was destroyed at Makuara Pattan, near Ravi river along the Indo-Pak Border, a senior police officer said here.
Inspector General of Police (Border Range) Amritsar Ishwar Chand said the rocket launcher was placed in the same building of Dina Nagar police station, in the stacks of sand bags, where the encounter took place on Monday last.
The IGP said after receiving information about the weapon, the police and Army took it to Makuara Pattan and dumped it in the ground where experts destroyed it.
He said preliminary investigations reveal that their targets were "very big". They first wanted to blow off Pathankot-Amritsar train, then they were to massacre passengers and then they had to kill the police personnel and their families after keeping them captive in the police station.
The gloves, which in the militants had in one of their hand, were made in Pakistan's Adiyas company, he said, adding that it further strengthened the theory that they came from Pakistan and were natives of that country.
